Typical Constructions

The following is basic information on the most

common CTS 15/16" (24mm) diameter composition

variable resistor constructions supplied to our

customers. Space limitations prohibit showing the

virtually thousands of additional constructions fabri-

cated to exacting customer specifications. For your

special applications the CTS engineering staff is

at your disposal for designing the best and most

economical construction to meet your requirements.

Vernier Constructions

This construction is designed for fine tuning

applications. It provides precision adjustments with a

vernier ratio of 6.6˚ or 12.5˚ per degree available in

51/2or 101/4turns.

Long Life Construction

This construction provides an extended life of 250,000

cycles (with a limited rotation angle) and is available

with resistance ranging from 10K ohm to 5 megohm,

linear tapers only. Consult CTS.
